  • Torsion of a Transversely Isotropic Elastic Half-Space
    Indentation Testing of Biological Materials, 2018
    Co-Authors: Ivan Argatov, Gennady Mishuris
    Abstract:

    In this chapter, we consider the circumferential tangential displacement field induced at the surface of a transversely isotropic Elastic Half-space by axisymmetric torsional loading, e.g., with the help of a rigid punch bonded to the Half-space surface. In particular, the axisymmetric problem of the torsion of an Elastic Half-space produced by means of a bonded flat-ended punch is studied in detail.

  • Adhesive Indentation of an Elastic Half-Space
    Indentation Testing of Biological Materials, 2018
    Co-Authors: Ivan Argatov, Gennady Mishuris
    Abstract:

    In this chapter, we study the axisymmetric problem of the so-called JKR-type adhesive indentation of a transversely isotropic Elastic Half-space. Explicit formulas are given for self-similar indenters. In the case of a paraboloidal indenter, the Johnson–Kendall–Roberts (JKR) theory is considered in detail. Approximate solutions are presented in the case of an annular area of contact.

  • Sticking (No-slip) Indentation of an Elastic Half-Space
    Indentation Testing of Biological Materials, 2018
    Co-Authors: Ivan Argatov, Gennady Mishuris
    Abstract:

    In this chapter, we study the axisymmetric problem of the so-called sticking (non-slipping) indentation of a transversely isotropic Elastic Half-space by means of an arbitrary indenter which produces a circular area of contact. Explicit formulas are given for self-similar indenters.

  • Slow vertical motions of an elliptic punch on an Elastic Half-space☆
    International Journal of Engineering Science, 2008
    Co-Authors: Ivan Argatov
    Abstract:

    The dynamic contact problem for a homogeneous, isotropic Elastic Half-space and a punch of an arbitrary base shape is studied. During the motion of the punch it is assumed that the contact area is fixed and there is no friction under the punch. An approximate solution to the problem is obtained under the assumption that the contact pressure under the punch is slightly varied during the time of travel of the Rayleigh wave along the distance equal to the diameter of the contact area. The solution of the problem of slow motions of a punch on an Elastic Half-space is reduced to the solution of the recurrent system of integral equations of the static contact problem. Asymptotic models of vertical motions of a flat-ended punch with an arbitrary base are constructed. The case of an elliptic punch is considered in detail.

  • Interaction of Several Dies on an Elastic Half-Space
    International Applied Mechanics, 2003
    Co-Authors: Ivan Argatov
    Abstract:

    A contact problem is solved for several rigid dies on an Elastic Half-space. Relationships between the generalized loads and generalized displacements of a large number of spaced dies are established. The interaction between flat-based dies is described in terms of their capacity characteristics. The general solution is constructed on the basis of Mossakovski's theorem. Explicit formulas are derived for a system of elliptic dies

  • Unsymmetrical Elastic stamp on a nonlocal Elastic Half-plane
    Computers & Structures, 1997
    Co-Authors: Reha Artan
    Abstract:

    Abstract The statical problem of an Elastic stamp on a nonlocal Elastic Half-plane is solved. The starting point is the solution of the problem of a rigid stamp on an Elastic Half-plane. This solution is given in the appendix. The classical solution of the Elastic stamp is obtained by making appropriate changes in the classical solutions of the rigid stamp. The classical and nonlocal problem of Elastic stamp has not yet been solved in the literature. The nonlocal solution of the problem is carried out by using the classical solution. The classical solution gives infinite stresses at the tips of the edges, but the nonlocal solution produces infinite stresses nowhere. This situation is shown by several diagrams.

  • Rectangular rigid stamp on a nonlocal Elastic Half-plane
    International Journal of Solids and Structures, 1996
    Co-Authors: Reha Artan, Tanju Yelkenci
    Abstract:

    First, the solution of the problem of a rectangular rigid stamp uniformly moving on an Elastic Half plane is given. Secondly, the solution is obtained for a motionless rectangular stamp on a nonlocal Elastic Half space. The finite distribution of the stress under the stamp has been compared with the unbounded stresses of local case.
